| Abstract: | The determination of COD Cr in wastewaters by using quickly opening tube method and MnSO 4 as a catalyst instead of Ag 2SO 4 is introduced.The method can reduce analytical cost and shorten analytical time to 12 min,its accuracy and delicacy are the same as the standard method.The method needs a small quantity of sample and has a rapid analytical speed.It is suitable for determination of a great quantity of samples. |
| Keywords: | COD Cr determination catalyst MnSO 4 and opening tube method |
